Someone says,“Time is money.” But I think time is    36  important than money. Why? Because when money is spent, we can get it back. However, when time is   37 , it’11 never   38 . That is   39   we mustn’t waste time. You know that   40 is usually limited（有限的）. Even a second is very important. We should make full use of our time to do    41   useful. But it is a pity that there are a lot of people who do not know the importance of time. They spend their limited time smoking，drinking and   42  . They do not know that wasting time means wasting part of their own   43 . In a word，we should save time，we shouldn’t    44  today’s work for tomorrow. Remember we have no time to   45 .
